Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically a lens processing clamping fixture. Background Technology

[0002] A spherical lens has a constant curvature from its center to its edge, while an aspherical lens has a continuously changing curvature from its center to its edge. Both spherical and aspherical lenses are commonly used in scientific research and medical fields. Spherical lenses do not require grinding during production, while aspherical lenses require grinding to change their curvature, necessitating the use of clamping fixtures during grinding.

[0003] In the existing technology, the processing of spherical lenses faces many challenges. Due to the wide variety of sizes of spherical lenses, when processing spherical lenses of different sizes, it is necessary to disassemble and replace the matching clamping fixtures. This process not only increases the complexity of the operation but also significantly reduces production efficiency. In addition, frequent changes to the clamping fixtures may lead to accelerated wear of the fixtures, thereby affecting the stability and accuracy of clamping.

[0004] Therefore, this utility model provides a lens processing clamping fixture to solve the above problems. Utility Model Content

Multiple sets of jaws are rotatably mounted on the multiple sets of first support rods and the multiple sets of second support rods. A screw is rotatably mounted inside the workbench and the base. A movable block is threadedly connected to the upper end of the screw. Multiple sets of connecting rods are rotatably mounted on the movable block, and the multiple sets of connecting rods are rotatably connected to the multiple sets of second support rods respectively.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a lens processing clamping fixture, such as Figure 1-5 As shown, the clamping fixture includes a worktable 1, with a machining groove 2 at the upper end of the worktable 1 and a movable groove 3 inside the upper end of the worktable 1. The upper opening of the movable groove 3 is connected to the machining groove 2. A clamping assembly is provided inside the worktable 1, including a base 4. The base 4 is fixedly installed inside the lower end of the worktable 1. Multiple sets of brackets 5 are fixedly installed on the upper side of the base 4. A first support rod 6 is rotatably installed on each set of brackets 5, and a second support rod 7 is rotatably installed on each set of brackets 5. The multiple sets of second support rods 7 and the multiple sets of first support rods 6 are arranged in parallel. Multiple sets of jaws 8 are rotatably installed on the multiple sets of first support rods 6 and the multiple sets of second support rods 7. A screw 10 is rotatably installed inside the worktable 1 and the base 4. A movable block 11 is threadedly connected to the upper end of the screw 10. Multiple sets of connecting rods 12 are rotatably installed on the movable block 11. The multiple sets of connecting rods 12 are rotatably connected to the multiple sets of second support rods 7 respectively. Limiting components are provided at the upper ends of the multiple sets of jaws 8 and inside the upper opening of the movable groove 3.

[0025] In use, the operator first places the unprocessed lens into the processing groove 2. The screw 10 rotates. Since the upper end of the screw 10 is connected to the movable block 11 by a thread, the rotation of the screw 10 causes the movable block 11 to slide downward. The downward sliding of the movable block 11 drives the multiple sets of second support rods 7 to rotate on the multiple sets of brackets 5 through multiple sets of connecting rods 12. Since multiple sets of jaws 8 are rotatably installed on the multiple sets of first support rods 6 and multiple sets of second support rods 7, the rotation of the multiple sets of second support rods 7 will drive the multiple sets of jaws 8 to rotate synchronously and approach. At the same time, the upper end of the multiple sets of jaws 8 is provided with limit components. The multiple sets of limit components slide close and clamp the side of the unprocessed lens, thereby enabling the clamping of lenses of different sizes and improving the practicality of the device.

[0026] The limiting component includes multiple sets of fixing blocks 13, which are fixedly installed on the opposite side of the upper end of multiple sets of jaws 8. Multiple sets of clamping plates 14 are movably installed at the upper opening of the movable groove 3. Each set of clamping plates 14 has a sliding groove 15 on the side opposite to the multiple sets of jaws 8, and the multiple sets of fixing blocks 13 are movably inserted into the multiple sets of sliding grooves 15.

[0027] When multiple sets of jaws 8 approach each other, multiple sets of fixing blocks 13 slide within multiple sets of sliding grooves 15, causing multiple sets of clamping plates 14 to move closer together as the multiple sets of jaws 8 slide, thus clamping and fixing the unprocessed lens.

[0028] A positioning seat 16 is fixedly installed at the lower center of the processing groove 2. The upper side of the positioning seat 16 is flush with the lower one-third height of the multiple sets of clamping plates 14.

[0029] The unprocessed lens is placed on the positioning seat 16, so that the sliders of the multiple sets of clamping plates 14 are close to the side of the lens on the positioning seat 16, thus avoiding the problem of position displacement or tilting and lifting on one side due to the lack of support on the lower side when clamping the lens.

[0030] Rubber elastic pads are glued to the upper side of the positioning seat 16 and the opposite side of the multiple sets of clamps 14.

[0031] The rubber elastic pad increases the friction between the positioning seat 16 and the multiple clamping plates 14 and the lens, improving the stability of clamping and preventing damage to the lens surface due to excessive clamping force, thus ensuring the processing quality of the lens. In addition, the rubber elastic pad also has a certain buffering effect, which can reduce the vibration and impact generated during processing to a certain extent, further protecting the lens.

[0032] A motor 9 is fixedly installed inside the base 4, and the upper output shaft of the motor 9 is fixedly connected to the lower end of the movable block 11.

[0033] By controlling the start and stop of the motor 9, the screw 10 can be rotated to raise and lower the movable block 11, thereby controlling the opening and closing of multiple sets of jaws 8 to clamp and release the lens. The operation is simple and quick.

[0034] The upper ends of the multiple sets of jaws 8 and the multiple sets of clamping plates 14 are located on the front, back, left, and right sides of the positioning seat 16, respectively.

[0035] This clamping fixture enables the lens to be clamped comprehensively and stably, ensuring that the lens will not wobble or shift during processing, thereby further improving processing accuracy and product quality.

[0036] Working principle:

[0037] When using this lens to process the clamping fixture, the operator first starts the motor 9. The output shaft of the motor 9 rotates, driving the screw 10 to rotate. Since the screw 10 and the movable block 11 are connected by a thread, the rotation of the screw 10 will cause the movable block 11 to slide downwards along the screw 10. As the movable block 11 slides down, multiple sets of connecting rods 12 will rotate accordingly. Since the multiple sets of connecting rods 12 are rotatably connected to multiple sets of second support rods 7, the rotation of the multiple sets of connecting rods 12 will drive the multiple sets of second support rods 7 to rotate on multiple sets of brackets 5. Since multiple sets of jaws 8 are rotatably mounted on multiple sets of first support rods 6 and multiple sets of second support rods 7, the rotation of multiple sets of second support rods 7 will cause the multiple sets of jaws 8 to rotate synchronously and move closer to each other. At the same time, the upper end of the multiple sets of jaws 8 is provided with a limit component to limit... The positioning assembly includes multiple sets of fixing blocks 13 and multiple sets of clamping plates 14. The multiple sets of fixing blocks 13 are fixedly installed on the opposite side of the upper end of the multiple sets of jaws 8, while the multiple sets of clamping plates 14 are movably installed at the upper opening of the movable groove 3, and a sliding groove 15 is opened on the side opposite to the multiple sets of jaws 8. When the multiple sets of jaws 8 rotate and approach, the multiple sets of fixing blocks 13 will slide in the multiple sets of sliding grooves 15, thereby driving the multiple sets of clamping plates 14 to move and approach as the multiple sets of jaws 8 slide. In this way, the multiple sets of clamping plates 14 can clamp and fix the side of the unprocessed lens placed on the positioning seat 16. When it is necessary to clamp lenses of different sizes, the operator only needs to adjust the rotation time of the motor 9 to control the downward sliding distance of the movable block 11 and the opening angle of the multiple sets of jaws 8, thereby realizing the clamping of lenses of different sizes.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
